Interacting Barrow holographic dark energy model in the presence of radiation and matter
Interacting Barrow holographic dark energy model in the presence of radiation and matter
We have studied the effect of radiation in the interacting barrow holographic dark energy model for a non-flat universe. For both open and closed universes, we have obtained the evolution equation for the density parameters for dark energy, dark matter and radiation for a specific kind of interaction among the seven possible linear interactions; the analysis with the remaining six interactions will be updated soon in this manuscript. We have then numerically solved those coupled differential equations to show their behaviour with the redshift parameter. We have also found different epochs corresponding to dark energy-dark matter, dark energy-radiation and dark matter-radiation crossings. We have also obtained various observational constraints for our interacting Barrow holographic dark matter model using the Cosmic chronometer data and BAO data. In the upcoming version of the manuscript, we will add the observational constraints of our model using Pantheon data, also several calculations of other interaction scenarios will be added.
